CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent application Ser. No. 61/552,030 entitled “ADAPTABLE SPREADER” filed on Oct. 27, 2011, the entirety of which is herein incorporated by reference.

ORIGIN

The innovation disclosed herein relates to a particulate dispersing apparatus and, more specifically, to a spreader having interchangeable inserts to accommodate the dispersement of different sized particulate material.

BACKGROUND

Traditional material spreaders have been designed to include a container, known as a hopper, from which particulate materials can be emptied slowly and evenly onto a spinning disk, called an impeller, so as to then be distributed in a pattern to a lawn or other like surface. Generally, the hoppers comprise side walls that taper inwardly from an open top to a flat, closed bottom through which one or more holes are pierced in such a location as to allow material to be emptied directly upon the surface of the spinning impeller. A problem with the traditional design is that the flat hopper bottom tends to gather material about its edges and upon its surface, oftentimes precluding complete emptying of the hopper, in what is known as bridging.

Another disadvantage to the traditional spreader is that although the traditional spreader has a means to adjust the output dispensing rate of the material, the traditional spreaders do not have a means to disperse particulate material that vary in size. For example, the traditional spreaders cannot adapt to disperse very fine particulate material, such as grass seed, up to larger particulate material, such as rock salt, stone, etc. in a uniform manner.

DETAILED DESCRIPTION

The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the subject innovation. It may be evident, however, that the innovation can be practiced without these specific details.

While, for purposes of simplicity of explanation, the one or more methodologies shown herein, e.g., in the form of a flow chart, are shown and described as a series of acts, it is to be understood and appreciated that the subject innovation is not limited by the order of acts, as some acts may, in accordance with the innovation, occur in a different order and/or concurrently with other acts from that shown and described herein. For example, those skilled in the art will understand and appreciate that a methodology could alternatively be represented as a series of interrelated states or events, such as in a state diagram. Moreover, not all illustrated acts may be required to implement a methodology in accordance with the innovation.

The innovation described herein discloses a particulate dispersement apparatus and, more specifically, a spreader capable of evenly and uniformly dispersing particulate material of various sizes (e.g., seed, fertilizer, rock salt, stone, etc.). In various aspects, the subject innovation includes various features not available in conventional spreaders.

Embodiments of the subject innovation include a spreader that can be used with any of a plurality of interchangeable and readily installable (e.g., snap-in) trays or inserts. This spreader can incorporate a hopper different from conventional hoppers in that it has no bottom or has a removable bottom, and is adapted to engage with any of the plurality of inserts. These trays or inserts can be self-cleaning hopper inserts or trays that can allow a user to effectively have a plurality of different spreaders in one, by changing inserts depending on the situation. For example, any of the plurality of inserts with unique drop hole patterns discussed infra can be used, as well as other variations that would be understood by a person of skill in the art in light of the teachings herein. In other aspects, the innovation can incorporate substantially any conventional drop hole pattern into a novel insert useable with the subject innovation. Further aspects can include conventional patterns modified to incorporate some or all the novel features discussed herein in connection with various inserts.

As described further below, different variations of hopper inserts are disclosed where each insert includes a different hole pattern, with each pattern configured to meet the specific demands of different materials, applications, and outputs. Although only a limited number of patterns are discussed, it is to be understood that other variations can be adapted for other purposes in light of the discussion herein.

Additionally, embodiments of the subject innovation address problems encountered by conventional systems (e.g., bridging), and can be “self-cleaning’ in that the configuration can allow material to flow unimpeded out of the hopper. The hopper portion of the subject innovation can be similar to the traditional design, except, as mentioned above, that its bottom can be open and in its place, any of a plurality of removable inserts can be introduced, for example, depending on the application or material. Unlike the flat bottoms of the traditional hoppers, the removable insert can be generally funnel-shaped (e.g., can be part of a pyramidal, conic, or other shape wherein the cross-section tends to decrease toward an apex, etc.), transitioning from the cross-sectional shape of the mating hopper at its periphery downwardly to an imaginary apex outside of its body. Because of the tapering of the insert, material in the hopper will move toward the apex as the material is pulled downwardly by gravity.

In various embodiments, the insert can further comprise a collection cup, which can be a downwardly extending portion of the insert. The collection cup can have one or more outlet holes through which material can exit the hopper. Because the inwardly tapered side walls of the cup can be vertically aligned with the apex of the insert (e.g., such that the apex is aligned above, below, or within the cup, etc.), gravity will cause material to flow into the cup and then through the one or more outlet holes. In those embodiments where multiple outlet openings may be required, all of those openings can exist within the confines of the collection cup, and material flow can be further directed by the inclusion of and shaping of housing material that can exist between each pair of openings. For example, in instances in which there is a surface between a pair of openings, that surface can be tapered downwardly toward an opening, rather than being horizontal. This feature can provide for more efficient dispensing of material in a variety of ways, for example, in that the tapered shape of the surface can prevent material from remaining on it. Because of this, all material can escape the hopper/insert assembly, in contrast to conventional systems.

In other aspects, the subject innovation can include an agitator to minimize bridging and facilitate proper material flow, such as but not limited to oscillating fingers described further below. In various embodiments, these oscillating fingers or another agitator can be incorporated into spreaders using interchangeable inserts, as well as into a “fixed” spreader. In various embodiments, the agitator can reside in the shut-off plate portion of the assembly. The fingers can be an upwardly protruding portion of the agitator, such as pins, etc., and can protrude upwardly away from said shut-off plate and through each of the drop holes. In aspects, the fingers can protrude through the drop holes a specified distance into the hopper insert or tray. The oscillating motion of the fingers can create air-gaps and can assist gravity in the process of feeding materials that otherwise have a tendency to bridge and therefore not flow properly. The oscillating motion of the fingers can encourage materials to move at a constant rate into the drop holes, thereby creating an even flow of the material onto the impeller (the spinning disk below the drop holes). This flow facilitates a superior spread pattern, even with very difficult to spread materials.

In other aspects, the innovation can also incorporate a floating gearbox. In these aspects, the “fixed” axle that has been the industry standard for commercial & professional gearboxes can be replaced by an axle that uses a novel parabolic drive to power the gearbox. This can reduce user effort in operation. Additionally, less space than that required for the packaging of current gear boxes will be required for the packaging of the new assemblies.

With reference now to the figures, FIG. 1 illustrates an example embodiment of a particulate dispersing apparatus 100 that is part of an innovative system and method for changing a particulate output of the dispersing apparatus 100 in accordance with aspects of the innovation. It is to be understood that the particulate dispersing apparatus 100 may be any type of particulate dispersing apparatus capable of dispersing particulate material, such as but not limited to a lawn seed/fertilizer spreader, a salt spreader, etc. In addition, the particulate dispersing apparatus 100 may be a walk behind type spreader, a hand-held type spreader, a tow-type spreader 200 having a connection device 202 to connect the spreader 200 to a vehicle, as shown in FIG. 2, etc. The example particulate dispersing apparatus 100 illustrated in FIG. 1 is a walk behind type spreader and will be used to describe the innovation disclosed herein. Thus, the example particulate dispersing apparatus 100 illustrated in FIG. 1 is for purposes of illustration only and is not intended to limit the scope of the innovation.

Referring to FIGS. 1 and 3-5, the example particulate dispersing apparatus 100, which as mentioned above is a walk behind spreader, includes a frame 102, a vessel or hopper 104 mounted to the frame 102 (see FIG. 4), a removable insert 106 disposed inside the hopper 104, a push handle 108 mounted to the frame 102, an open-close/adjustment (shut-off) assembly 110, a pair of wheels 112, a dispersing mechanism 114 to disperse product from inside the hopper 104, and a gear box 116 operatively connecting the wheels 112 and the dispersing mechanism 114 via an axle 118 and a gear/impeller shaft 120.

Referring to FIG. 5, the open-close/adjustment assembly 110 includes a gauge 122, an adjustable lever 124 connected to the gauge 122, a rod 126 connected to the lever 124 at one end and to a shut-off/adjustment plate described further below at an opposite end. When the lever 124 is in a first (full forward) position, as shown in FIG. 5, the open-close/adjustment assembly 110 is in a full closed position. In this position, the shut-off/adjustment plate of the removable insert 106 is in a full closed position thereby preventing any particulate material from exiting the dispersing apparatus 100. Conversely, when the lever 124 is in a second (full rearward) position, the open-close/adjustment assembly 110 is in a full open position. In this position, the shut-off/adjustment plate of the removable insert 106 is in a full open position, thus, allowing a maximum flow of particulate material to be dispersed by the dispersing apparatus 100. The shut-off/adjustment plate of the removable insert 106 can be operated at any position between the full closed position and the full open position to thereby vary the amount of particulate material dispersed by the dispersing apparatus 100.

Referring to FIGS. 6A-6D, the hopper 104 has a square type shape, as viewed from the top, but it is to be understood that the shape of the hopper 104 can be any shape, such as but not limited to rectangular, circular, etc. An opening 128 is defined in a bottom 130 of the hopper 104 and is adapted to receive a bottom portion of the removable insert 106 as will be described further below. Attachment apertures 132 are defined in a ridge 134 in two or more sides of the hopper 104 and are adapted to receive a fastening device to secure the removable insert 106 to the hopper 104.

Referring to FIGS. 7A-7C, as mentioned above, the dispersing apparatus 100 includes one or more removable inserts 106 disposed inside the hopper 104. The removable insert 106 is configured to have a shape similar to an inside shape of the hopper 104. In the example illustrated in the figures, as viewed from the top in FIG. 6B, the removable insert 106 has a square shape, but can be configured to have any shape to conform to the shape of the hopper 104, such as but not limited to rectangular, circular, etc. In addition, the removable insert 106 has a concave or funnel shape whereby a bottom surface 136 transitions downward from a perimeter 138 toward one or more openings 140 defined in the bottom surface 136 of the removable insert 106. This configuration facilitates optimal flow of the particulate material out of the hopper 104, as will be illustrated further below.

The removable insert 106 further includes attachment slots 142 defined in the perimeter 138 of the removable insert 106, which align with the attachment apertures 132 defined inside the hopper 104 to facilitate attachment of the removable insert 106 to the hopper 104. To secure the removable insert 106 inside the hopper 104, the removable insert 106 is placed inside the hopper 104 as shown by the arrows A in FIG. 8 such that a bottom portion 144 of the removable insert 106 extends into the opening 128 defined in the hopper 104, which is best shown in FIG. 4. Once properly inserted, the perimeter 138 of the removable insert 106 engages the ridge 134 inside the hopper 104 such that the removable insert 106 sits inside the hopper 106, as shown in FIG. 9. In addition, once the removable insert 106 is properly inserted, the attachment slots 142 defined in the removable insert 106 are aligned with the attachment apertures 132 defined in the hopper 104.

A fastener 146 is inserted into and through both the attachment slots 142 and the attachment apertures 132 to secure the removable insert 106 to the hopper 104. The fastener may be any type of mechanical fastener, such as but not limited to, a snap type fastener, a clip, a screw, a nut and bolt, etc. An example of a snap type fastener is illustrated in FIG. 10. The fastener 146 includes a head 148 and a body 150 having a pair of legs 152 separated by a gap 154. The head 148 is pitched to conform to a pitch of the hopper 104 and the removable insert 106 to insure that the removable insert 106 sits flush against the inside surface of the hopper 104. This head 148 configuration insures that the perimeter 138 of the removable insert 106 and/or the fastener 146 do not impede the flow of particulate material out of the hopper 104. The legs 152 of the fastener 146 compress toward each other when the fastener 146 is inserted into and removed from both the attachment slots 142 and the attachment apertures 132. Once fully inserted, the fastener 146 secures the removable insert 106 to the hopper 104.

Referring to FIGS. 7B and 9, a shaft aperture 154 is defined in the bottom portion 144 of the removable insert 106 and is adapted to receive the gear/impeller shaft 120 that extends upward from the gear box 116 into the hopper 104. A batwing-like shaped bushing placed over the gear/impeller shaft and engages the removable insert 106 provides support for the gear/impeller shaft 120 and is removable to allow replacement of the removable insert 106, as will be described further below.

Referring to FIG. 11, as mentioned above, the removable insert 106 has a concave or funnel like shape. In other words, the bottom surface 136 of the removable insert 106 slopes in a downward direction from the perimeter 138 toward the one or more openings 140 defined in the removable insert 106. This shape facilitates the flow of the particulate material through the one or more openings 140 and out of the hopper 104. Specifically, the particulate material easily flows in the direction indicated by the arrows A1 in FIG. 11.

Thus, as mentioned above, the innovative configuration addresses bridging problems encountered by conventional spreader systems. In addition, the innovative configuration can be “self-cleaning” in that the configuration allows particulate material to flow unimpeded out of the hopper. Still further, the innovative particulate dispensing system and method includes interchanging removable inserts whereby each removable insert includes one or more openings, thus, forming a specific hole pattern configured to meet specific demands of different materials, applications, and outputs. Disclosed below are several example embodiments of removable inserts having different hole patterns and, thus, different particulate applications and outputs. It is to be understood, that the examples described herein are for illustrative purposes only and are not intended to limit the scope of the innovation.

Referring to FIG. 12, a first example embodiment of a removable insert 1200 is illustrated in accordance with an aspect of the innovation. The removable insert 1200 includes multiple (i.e., three) small openings 1202 thereby forming a first hole pattern 1204, whereby the multiple openings 1202 have a predetermined size. Thus, the removable insert 1200 is configured for use with particular material that corresponds to the size of the multiple openings 1202, such as but not limited to, fertilizers, lawn chemicals, ice melt, and other materials for general purpose use.

Referring to FIG. 13, a second example embodiment of a removable insert 1300 is illustrated in accordance with an aspect of the innovation. The removable insert 1300 includes multiple (i.e., two) larger openings 1302 thereby forming a second hole pattern 1304 that produces a high particulate output. Because the openings 1302 are larger than the openings 1302 described above, the hole pattern 1304 is more suitable for use with larger particulate material such as rock salt, damp sand, and/or, organic fertilizers that have a larger particle size and/or are most effectively distributed at a high application rate. Thus, the removable insert 1300 is for applications that require a high volume output of particulate material. In addition, a spread pattern generated by the removable insert 1300 can be an approximately 180 degree semi-circle from the center of the gearbox, forward or opposite to the operator or user, and can be in line with the direction of the operation on a walk behind spreader, or rearward or opposite to the operator and in line away from with the direction of the operation on a tow spreader.

Referring to FIG. 14, a third example embodiment of a removable insert 1400 is illustrated in accordance with an aspect of the innovation. The removable insert 1400 includes multiple (i.e., two) medium sized openings 1402 thereby forming a third hole pattern 1404 that produces a low volume particulate output. Because the openings 1402 are smaller than the openings 1302 described above, the hole pattern 1404 is more suitable for use with smaller particulate material such as fine grass seeds (e.g., Bermuda), low application rate chemicals (pesticide/herbicide), the application of fire ant baits, and very fine particulate and/or granular materials.

Referring to FIG. 15, in another example embodiment, the particulate dispersing apparatus 100, 200 illustrated in FIGS. 1 and 2 and described herein may include a shut-off/adjustment plate 1500 that includes openings 1502. The openings 1502 are similar in quantity, size and shape to the openings 1202, 1302, 1402 described above. In the example embodiment illustrated in FIG. 15, the shut-off/adjustment plate 1500 has openings 1502 similar in quantity, size and shape to the openings 1202 described in the first example embodiment above and is, thus, for illustrative purposes only and is not intended to limit the scope of the innovation.

The shut-off/adjustment plate 1500 is connected to the open-close/adjustment assembly 110 via the connector rod 126 described above. As described above, when the lever 124 is in a first (full forward) position, as shown in FIG. 5, the open-close/adjustment assembly 110 is in a full closed position. In this position, the shut-off/adjustment plate 1500 covers the openings 1202, 1302, 1402 in the corresponding removable insert and is, thus, in a full closed position thereby preventing any particulate from exiting the dispersing apparatus 100. Conversely, when the lever 124 is in a second (full rearward) position, the open-close/adjustment assembly 110 is in a full open position. In this position, the shut-off/adjustment plate 1500 of the removable insert 106 is not covering the openings 1202, 1302, 1402 of the corresponding removable insert, thus, allowing a maximum flow of particulate to be dispersed by the dispersing apparatus 100. In other words, the holes 1502 in the shut-off/adjustment plate 1500 are aligned with the openings 1202, 1302, 1402 in the corresponding removable insert thereby allowing particulate material to flow out of the vessel 104. In addition, the shut-off/adjustment plate 1500 of the removable insert 106 can be operated at any position between the full closed position and the full open position to thereby vary the amount of particulate material dispersed by the dispersing apparatus 100.

In yet another embodiment, illustrated in FIGS. 16-18, the particulate dispersing apparatus 100, 200 illustrated in FIGS. 1 and 2 and described herein may include a shut-off/adjustment plate 1600 that includes openings 1602 and agitator pins 1604. The agitator pins 1604 are disposed at an edge of the one or more openings 1602. Thus, the agitator pins 1604 are also disposed at an edge of the openings 1202, 1302, 1402 of the corresponding removable insert. During operation of the particulate dispensing apparatus 100, the agitating pins 1604 oscillate, which agitates and feeds the particulate material out of the openings in the removable inserts and the shut-off/adjustment plate 1600 thereby, creating a more uniform and consistent flow of particulate material to the impeller, thus, creating a better spread of particulate material across a spread pattern. A collar 1606 can be included and attached to a bottom of the vessel to provide additional support for the shut-off/adjustment plate 1600.

Referring to FIG. 19, a method of configuring a particulate material dispensing apparatus to accommodate different sized particles is illustrated. At 1902, a vessel that holds and dispenses particulate material is provided. At 1904, a removable insert is placed into an inside of the vessel, whereby the removable insert has a hole pattern that includes a least one opening to accommodate the dispensing of a particulate material having a particular size. At 1906, the particulate material is dispersed. At 1908, the removable insert is removed from the vessel. At 1910, a different removable insert is placed into the vessel, whereby the different removable insert has a different hole pattern distinct from the hole pattern of the removable insert. At 1912, a different size particulate material is dispersed. The different size of the different particular material corresponds with the different hole pattern of the different removable insert. Further, the different particular size is distinct from the particular size of the particulate material that corresponds with the removable insert.

Although multiple features have on some occasions been discussed herein as being incorporated into single embodiments in order to convey aspects of the subject innovation concisely, it is to be appreciated that these features are independent, and various embodiments can incorporate some of these features without others (e.g., novel drop hole designs, even if used in connection with fixed bottom hoppers; agitators; interchangeable inserts; floating gearbox; etc.) as will become evident from the description below.
